Professional Applications & Engineering Value
This M4 x 0.3mm metric flange nut is engineered for ultra-precision lead screw assemblies where backlash and positional accuracy are critical. The Acetal Plastic material offers inherent lubrication properties, reducing the need for external lubricants and minimizing particulate contamination in clean environments like medical devices, laboratory automation, and optical positioning systems. Its metric trapezoidal thread form ensures smooth, consistent engagement with mating screws, providing precise linear motion control. The right-hand thread direction and single-start design deliver predictable, repeatable movement, solving common challenges of vibration loosening and wear in precision motion control applications.
Specification Summary & Compliance
This nut features an M4 thread size with a 0.3mm pitch following metric trapezoidal thread standards. It maintains precise dimensional tolerances suitable for ultra-precision lead screw applications. The component is manufactured from Acetal Plastic and is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and material reliability for industrial use.
